As seen on the phases above, this project is really a partial review for roads. Afull review, which is beyond this project’s scope, would be to actually review a road’s geometry and tags (name, etc) with local or ground knowledge, and finally deleting the “tiger:reviewed=no”tag. Important: the “tiger:reviewed=no” tag was assigned to all TIGER roads from the beginning by OpenStreetMap. The idea is to have mappers remove this tag once they fully review a road with local or ground knowledge. So leave it for roads you just partially reviewed!

Setting Up Your Work Environment

After PHASE 1 is finished: Pick a Municipio you’d like to contribute to. First, take a look at the PR TIGER Fixup Progress Map to know which municipios are “Up for grabs”. Now, still in the map, press the “UPDATE MAP” button to reserve a municipio by filling out a simple form; no login is required. This is the same form you’ll come back later to keep updating the percentages shown on the map.

Use a grid to guide you along your municipio. Download here. This is a GPX format layer that you can bring up as a reference in iD or JOSM. Use it to go row by row, west to east (or viceversa) covering all places. See AppendixAat the end of this document to to learn about adding it to iD or JOSM.

Prepare your editing environment. Open up iD or JOSM, and zoom to your municipio. Add your GPX layer grid as an overlay. Add imagery and other layers as references as detailed in the next section...

Still not sure about ESRI’s terms of use for this one:2009-10 Aerial Photography (Escuela Graduada de Planificación - Universidad de Puerto Rico Recinto de Río Piedras) hosted by Esri ArcGIS Online – World Imagery Basemap. In JOSM: adda TMS and paste this url: http://services.arcgisonline.com/ArcGIS/rest/services/World_Imagery/MapServer/tile/{zoom}/{y}/{x}. In iD, add it as a Custom background pasting the same link as above.

Road data:

US Census TIGER Roads (for tagging road names). Can be downloaded and there are web services available, but they can be easily previewed in this web map: TIGERweb.

Carreteras Estatales, Autoridad de Carreteras y Transportación. These are state owned roads and can be downloaded here in “El Portal de Datos Gubernamentales de Puerto Rico” as a KML to quickly view in Google Earth or as a shapefile. This dataset is maintained by the local government. Although roads in this dataset have good positional accuracy, it doesn’t mean is more “truthful” than TIGER.

Some Tips

FIXING

Scenario

Action

Road is misaligned (outside road area as shown on imagery).

With imagery on the background, align it by dragging it or adding/deleting nodes as you think necessary. I always try to not delete whole roads or segments and rather work with what’s there. That way you preserve tags and connectivity.

Entire road or a segment in reality doesn’t exist.

Remove it!

UPDATING

Scenario

Action

There’s a new road to map!

Zoom into the imagery as adequate, make sure to connect the new road to an existing one (just click anywhere on top of it), and draw your new road. Now add some basic tags to it (basic tags if applicable: highway, name, ref, oneway). For example: “highway=residential” and “name=Calle Constitución”. If you don’t know the new road’s name based on local knowledge, look up what US Census TIGER roads say: TIGERweb (use only public domain sources please, not Google Maps). In PR it’s common to see lower class roads without names. Alternately, there are roads with two names. For this, other than the “name” tag, add this other tag: “ref=ThatOtherName”. Side note: you’ll see existing roads in OSM with “tiger=this” or “tiger:something=that” tags, you don’t have to add these.

An existing road in OSM has an old name, which is not the name people use today. Commonly found in gated communities. First the road was known as “Calle 1” and now is “Calle Picaflor”.

What I would do at least is have this tags: “name=Calle Picaflor” and “alt_name=Calle 1”. What you people think?
